Chosen Solution

Hi all, am hoping you can help me with my dilemma here. I bought an iBook off of eBay a couple of years ago and battery doesn’t hold charge. The adapter light turns from orange to green then back to orange erratically. Battery icon showed either ‘X’ or 0%. I replaced the DC inboard because the adapter pin got stuck in there. It works perfectly when plugged in (apart from erratic battery behaviour). I have just bought a new battery hoping it would solve my problem. But here’s the thing:

  1. When I plugged in the AC adapter, it turns orange the whole time it’s stuck in but it doesn’t charge the battery.
  2. Battery stays at 29% and I got two lights on the battery indicator.
  3. Coconut battery says I have 29% as well but it tells me that battery is not charging.
  4. System Profiler also says battery is connected but doesn’t show as charging.
  5. I left the laptop on sleep and hoping it would charge overnight but nothing happened the next day. It is still 29%
  6. I tried to turn laptop on without the AC adapter, but it won’t turn on, not even a blink.
  7. I have reset PRAM, NVRAM and PMU to no avail. Are these signs of bad logic board? Thanks guys!

The first thing I would do is replace the DC_IN board from a suppliers with a good reputation. Who knows what you got off of eBay (the part probably came off a non-working machine and they had no way to test the parts).
